A Dynamic Breathing Lung Chip for Precise Evaluation of Inhaled Drug Efficacy and Airway Epithelial Responses.

Inhaled therapy has become a crucial treatment option for respiratory diseases like asthma, cystic fibrosis, and chronic obstructive pulmonary disease (COPD), delivering drugs directly to bronchial and alveolar tissues. However, traditional static cell models, while valuable for studying pharmacokinetics (PK) and pharmacodynamics (PD), fall short in replicating the dynamic nature of physiological breathing. In this study, we present a breathing lung chip model that integrates a dynamic breathing mechanism with an air-liquid interface (ALI) culture environment to overcome these limitations.

Mitochondrial Plasticity and Glucose Metabolic Alterations in Human Cancer under Oxidative Stress-From Viewpoints of Chronic Inflammation and Neutrophil Extracellular Traps (NETs).

Oxidative stress elicited by reactive oxygen species (ROS) and chronic inflammation are involved both in deterring and the generation/progression of human cancers. Exogenous ROS can injure mitochondria and induce them to generate more endogenous mitochondrial ROS to further perpetuate the deteriorating condition in the affected cells. Dysfunction of these cancer mitochondria may possibly be offset by the Warburg effect, which is characterized by amplified glycolysis and metabolic reprogramming.

Long-Term Outcomes of Esophageal Squamous Neoplasia with Muscularis Mucosa Involvement after Endoscopic Submucosal Dissection.

Ambiguity exists over treatment and surveillance strategies after endoscopic submucosal dissection (ESD) for esophageal squamous cell neoplasia (ESCN) with unfavorable histologic features. This study investigated the long-term outcomes of ESD in high-risk ESCN patients. We retrospectively included early ESCN patients treated with ESD at two medical centers in Taiwan between August 2010 and December 2023.

Cytotoxic T-lymphocyte antigen 4 polymorphisms and breast cancer susceptibility: Evidence from a meta-analysis.

Background: Cytotoxic T-lymphocyte antigen 4 (CTLA-4) is an immune checkpoint and regulates the immune function of T cells. However, previous findings regarding the association of CTLA-4 polymorphisms and breast cancer remain inconclusive. Therefore, we performed a meta-analysis to investigate the potential effects of five polymorphisms (-1722 T/C, -1661 A/G -318 C/T, +49 A/G, and CT60 A/G) in the CTLA-4 gene on breast cancer susceptibility.

Large-Scale Single-Nucleus RNA Sequencing Compatible with Complex Archived Samples.

Transcriptome profiling at single-cell resolution allows us to identify and assess functional cell types and cellular states, including those within degenerating ocular tissues in retinitis pigmentosa. The technology is particularly valuable when studying tissues with high cellular heterogeneity, or when specific cell types are of interest. In this chapter, we introduce a detailed protocol of a medium-throughput single-nucleus RNA sequencing technique that utilizes frozen tissue as input sample.

Glutathione peroxidase 4 expression predicts poor overall survival in patients with resected lung adenocarcinoma.

This study aimed to evaluate the protein expression of glutathione peroxidase 4 (GPX4) in resected non-small cell lung cancer (NSCLC). The clinical relevance and prognostic significance of GPX4 expression were analyzed. We reviewed patients with resected NSCLCs at Taipei Veterans General Hospital between September 2002 and January 2018.

Drainless thoracoscopic surgery should be avoided in primary spontaneous pneumothorax with pleural adhesion.

Objectives: Drainless thoracoscopic surgery, defined by omitting chest drain after surgery, has been demonstrated to be feasible in selected patients for pulmonary resection. However, drainless procedure for the treatment of primary spontaneous pneumothorax has raised concerns for its safety and thus has been less often reported. We aimed to share our preliminary experience regarding how to select patients with spontaneous pneumothorax for this procedure.

Endoscopic Screening for Second Primary Tumors of the Esophagus Among Head and Neck Cancer Patients.

Malignancies of the head and neck (HN) region and esophagus are among the most common cancers worldwide. Due to exposure to common carcinogens and the theory of field cancerization, HN cancer patients have a high risk of developing second primary tumors (SPTs). In our review of 28 studies with 51,454 HN cancer patients, the prevalence of SPTs was 12%.

Molecular target therapeutics of EGF-TKI and downstream signaling pathways in non-small cell lung cancers.

Lung carcinoma (LC) is the third most common cancer diagnosis and accounted for the most cancer-related mortality worldwide in 2018. Based on the type of cells from which it originates, LC is commonly classified into non-small cell lung cancers (NSCLC) and small cell lung cancers (SCLC). NSCLC account for the majority of LC and can be further categories into adenocarcinoma, large cell carcinoma, and squamous cell carcinoma.

Heart rate variability (HRV) signals have been used to index autonomic activity and arousal levels towards visual stimuli. The current research aimed to examine the influence of body mass index (BMI), disordered eating behaviors, and sex on the HRV reactivity to food in a nonclinical sample.

Vicryl Mesh Coverage Reduced Recurrence After Bullectomy for Primary Spontaneous Pneumothorax.

Background: Although thoracoscopic stapled bullectomy is a standard procedure for primary spontaneous pneumothorax (PSP), the postoperative recurrence rate is high. We investigated whether using a Vicryl (Ethicon, Somerville, NJ) mesh to cover the staple line after bullectomy reduces the postoperative recurrence rate.

Methods: Our single-blind, parallel-group, prospective, randomized controlled trial at 2 medical centers in Taiwan studied patients with PSP who were aged 15 to 50 years and required thoracoscopic bullectomy.

Are there causal relationships between attention-deficit/hyperactivity disorder and body mass index? Evidence from multiple genetically informed designs.

Background: Attention-deficit/hyperactivity disorder (ADHD) and body mass index (BMI) are associated. However, it remains unclear whether this association reflects causal relationships in either direction or confounding. Here, we implemented genetically informed methods to examine bidirectional causality and potential confounding.

Generation of osimertinib-resistant cells from epidermal growth factor receptor L858R/T790M mutant non-small cell lung carcinoma cell line.

Background: Lung cancer contributes to high cancer mortality worldwide with 80% of total cases diagnosed as non-small cell lung cancer (NSCLC). Epidermal growth factor receptor (EGFR) tyrosine kinase (TK) domain serves as a druggable target in NSCLC patients with exon 19 deletion and L858R mutation. However, patients eventually succumbed to resistance to first- and second-generation EGFR-TK inhibitors through activation of T790M mutation.
